Zou Yan’s “Five Virtues and Cyclicals” Theory: Historical Cyclicism from a Wu Xing (Five Elements) Perspective

Brief Introduction

The "Five Virtues and Cyclicals" theory (Wu De Zhong Shi) is a political philosophical theory proposed by Zou Yan, a prominent figure of the Yin-Yang School (Yin Yang Jia) at the end of the Warring States period. This theory links the Five Elements (Metal, Wood, Water, Fire, Earth) to the rise and fall of dynasties, positing that history does not progress linearly but evolves cyclically based on the principles of the Five Elements overcoming each other (e.g., Water overcomes Fire, Earth overcomes Water) or generating each other. This学说 provided a cosmological justification for the political legitimacy of the Qin unification of the Six States and deeply influenced the official ideology of the early Han Dynasty. In the Book of Han, this theory serves as a crucial thread for understanding how Dong Zhongshu integrated Yin-Yang and the Five Elements to construct a new Confucian system under the backdrop of Emperor Wu of Han’s policy to "abolish the hundred schools and respect only Confucianism."

Core Knowledge Points

1. The Companion System of "Virtue," "Color," "Sound," and "Number"

Zou Yan not only established the correspondence between dynasties and specific "Virtues" (De) but also constructed a comprehensive symbolic system:
* Qin as Water Virtue: The Qin Dynasty favored black (the color of Water) and implemented harsh, stern governance, corresponding to the North and Winter.
* Han as Earth Virtue or Fire Virtue: The early Han Dynasty largely inherited Qin institutions and temporarily continued the Qin’s Water Virtue. However, during Emperor Wu’s reign, scholars like Dong Zhongshu argued that the Han was a new dynasty that had "received the Mandate from the Qin." Since Earth overcomes Water, they proposed redefining the Han as Earth Virtue. Earth favors yellow, so during Emperor Wu’s reign, yellow became the preferred color for clothing and flags to signify the transfer of the Mandate of Heaven.

2. The Logic of Overcoming and Generating

Overcoming (Ke Dai)*: The mainstream view holds that dynastic succession follows the principle of "overcoming." For example, the Zhou Dynasty was Fire Virtue, and the Qin was Water Virtue (Water overcomes Fire); the Qin was Water Virtue, and the Han is Earth Virtue (Earth overcomes Water).
Generating (Jian Dai): Later developments included the "Three Traditions" (San Tong*) theory, which suggested that dynastic succession sometimes follows the principle of "generation" (e.g., Fire generates Earth), reflecting the continuity of historical development rather than mere violent replacement.

3. "Correcting the Calendar, Changing Colors, and Distinguishing Institutions"

Dynastic transition was not merely a handover of power; it required "corrections" to the calendar, clothing colors, and ritual systems (Gai Zheng Shuo, Yi Fu Se, Shu Zhi Du) to demonstrate the transfer of the Mandate of Heaven and secure political legitimacy.

Connections to the Book of Han

The Book of Han frequently mentions the "Five Virtues and Cyclicals," particularly in the memorials of Dong Zhongshu, Liu Xiang, and others, as well as in the Annals of Sacrifices (Jiao Si Zhi).

1. *The Establishment of "Earth Virtue" in the Annals of Sacrifices***:
During Emperor Wu’s reign, the Grand Minister welcomed a jade chi (a mythical sea creature) under the sacrificial bridge. The Historian Li Ssu stated: "Last year we found white gold in Yong, and now we have found jade in the Han River; the virtue of the land is beautiful." This event was interpreted as an auspicious omen manifesting the "Earth Virtue." Subsequently, the court formally "corrected the calendar, changed the color of garments, and favored yellow," marking the official transition of the Han Dynasty from "inheriting the Qin’s Water Virtue" to "Earth Virtue." The Book of Han details this process, reflecting how Five Elements theory directly intervened in the highest state rituals and political decision-making.

2. *Dong Zhongshu’s Thoughts in the Biographies of Gongsun Hong, Bo Zhi, and Er Kuan***:
Dong Zhongshu incorporated Yin-Yang and the Five Elements into the Confucian system, proposing the theory of "Moral Resonance between Heaven and Mankind" (Tian Ren Gan Ying). He argued that if an emperor’s governance lacked virtue, Heaven would issue warnings through disasters and anomalies (e.g., solar eclipses or earthquakes corresponding to Five Elements imbalances). The underlying logic of Dong Zhongshu’s memorials on disasters in the Book of Han is precisely the correspondence between "Virtue" and "Heavenly Dao" found in the "Five Virtues and Cyclicals" theory, providing a theoretical foundation for the Han political ethic of "matching Virtue with Heaven."

3. The Theoretical Basis for Wang Mang’s "Abdication":
The Book of Han: Biography of Wang Mang records that when Wang Mang usurped the Han, he claimed that the "Earth Virtue" had reached its zenith and should follow the principle of Five Elements overcoming or generating. Specifically, while Wang Mang initially justified his assumption of power by citing the "Five Virtues" theory to argue that he was receiving the Mandate of Heaven, the specific elemental shift is debated: Wang Mang claimed the Xin Dynasty would succeed the Han (Earth) with "Metal Virtue" (since Metal is generated by Earth), though some interpretations suggest he was transitioning the "Earth" cycle. Regardless of the specific elemental classification, the Book of Han clearly illustrates how this theory was used in the struggle for political legitimacy, with Wang Mang adopting titles like "An Han Gong" (Prince Who Pacifies the Han) before declaring himself Emperor.

Conclusion

Although the "Five Virtues and Cyclicals" theory is not a scientific historical perspective, it is a crucial component of ancient Chinese political philosophy. It provided "legitimacy" for dynastic transitions through cosmic order. In the Book of Han, this manifests as institutional changes, the interpretation of auspicious omens, and the integration of thought. Understanding this theory is the key to grasping Han Dynasty political culture.
